This fixes https://bugs.llvm.org/show_bug.cgi?id=40337. Previously, it was always assumed that relocations referenced symbols in the static symbol table. Now, if the Link field references a section called ".dynsym" it will look up these symbols in the dynamic symbol table. This patch is heavily based on D59097 by James Henderson Differential revision: https://reviews.llvm.org/D66532 llvm-svn: 369645
